<p>Mark,</p>
<p> We humans many times make quite a stumble when we
take a big new step (grid tied solar plus L-ion storage with the
brains to manage all of it). I agree with you on one hand, we'll
probably screw-up the first few iterations. On the other hand I
feel pretty confident that my sensor laden, computer driven,
signal processing, technology burdened truck will get me from
point A to point B with few worries and for many miles. I think
we'll figure this out as there is a very powerful incentive to do
so.</p>

<p>What could be simpler?</p>
<p>For some reason I can't help think of the Great Leap Forward in
Chine where Mao had all the peasants gathering up all the iron
objects and melting them down in small furnaces to help increase
steel production. Of course none of the "steel" was any good.</p>
<p>I guess it is because here I see a bunch of great industrial
control equipment stuffed into a tiny box and dropped in
someones basement. That's alot of stuff waiting to break or hang
up or reset or something.</p>
<p>I really have to wonder what the operating state of this piece
of equipment will be in 3 years and if still operational, how
many person-hours of support and maintenance will have been
expended.</p>

<div>It's a Radian, the batteries are Sony, there's a PLC in
the door controlling everything, and a Vera Z-Wave
controller for the programmable outlets.</div>
<div>The BMS is on the door, connected by the long cable you
see at the bottom. It's not really long enough, which I
complained about.</div>
<div>The transfer switch is a Generac component, very reliable
unit, rated at 200A.</div>
<div>There is a DIN rail next to the inverter that holds all
the internal wiring, metering, external connections.</div>
<div>One thing I would advocate, never try to make any
connections with this unit powered up. It is very tight in
there and the risk of touching a live terminal is high.</div>
<div>There is a 200A main breaker and a battery breaker, which
is software controlled for powering down from the front
panel. Startup requires holding in a DC breaker for the
electronics for a few seconds then engaging the main battery
breaker. The instructions says five seconds but I find it
takes about 15.</div>
